Miguel de Icaza, founder of Xamarin and lead developer of the Mono open-source implementation of Microsoft's .NET platform, announced on his blog today that the third major revision of the Mono framework is now available. Mono 3.0 was released on GitHub on October 18. It adds support for some of the most recently added key features of the .NET platform, incorporates Microsoft's open-source framework for Web development, and beefs up the capabilities of Mono on Mac OS X and iOS. It also lays the groundwork for much more rapid development of features for the Mono platform going forward.
